WHAT IS A "JAMMER"?


Cell phone jammers are devices that create a temporary "dead zone" to all cell phone in their immediate proximity.
A cell phone jammer is an instrument used to prevent cellular phones from receiving and transmitting the mobile signals to a base station. When used, the jammer effectively disables cellular phones in the area.
Other types of jammers include radar jammer
and radio jammer


SIZE OF A JAMMER


Some cell-phone jammers are made to look like actual phones. Others are briefcase-sized or larger. The biggest jammers used by police and the military can be mounted in vehicles for convoy security.


WHY ARE JAMMERS USED?


A phone jammer provides the ultimate solution in any area where cellular communications frequently cause nuisance either by loud incoming call rings or resulting loud telephone conversations.
Cell phone jamming devices were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists. Examples include:securityzonespublictransport,,classrooms, temples,tv & radio stations,jails,govt.buildings,military bases,industries etc.   



CONCLUSION


With the exception of Asian countries blocking cell-phone services by the general public is against the law in most countries like The United States, United Kingdom, Australia.
Every technology has good aspect as well as bad aspect
the important thing is ,how we are using it.

Maybe someday governments will relax their restrictions on jammers and they will become standard in places like churches, movie theaters and courthouses. Until then, only government personnel. and outlaw jammers will be able to enjoy some peace and quiet at the movie theater or the ride via public transportation to work
